Skin Barrier Lipids (N/A)

Target: N/A
Molecular classification: Lipid, Ceramides, Cholesterol, Free Fatty Acids

Overview

Skin barrier lipids are a complex mixture of ceramides, cholesterol, and free fatty acids located in the stratum corneum. They form a lamellar structure that prevents water loss, protects against environmental irritants, and maintains skin hydration. Disruptions in lipid composition can lead to dry skin, eczema, and other skin conditions. Topical application of lipids can restore barrier function.

Other names: Stratum Corneum LipidsIntercellular LipidsEpidermal Lipids

Mechanism of action

Topical application replenishes depleted lipids, restoring the lamellar structure and barrier function of the stratum corneum, reducing water loss and preventing irritant penetration.
